These unpatented hearing aids come with long-lasting rechargeable solar batteries that can make the technology accessible to millions of hearing-impaired across the world.

Solar ear is a Brazilian social business that manufactures, assembles and distributes digital hearing aids with solar battery chargers based on a technology that is shared freely. These batteries,costing only upto $0.50 more than disposable alternatives, last up to 3 years as opposed to approximately one week. They are also compatible with 95% of hearing-aids on the market, greatly reducing reliance on expensive and polluting, Zinc-air batteries. Through its integrated approach encompassing detection, research, education, equipment and therapy, Solar Ear has developed a holistic solution to hearing loss. Moreover, by employing young deaf people in the manufacturing process, the company is also working to transform the way society views the skills of people with disabilities.

The innovation

THE INNOVATION

The WHO estimates that 360 million people suffer from hearing loss globally. In developing countries, approximately 32 million hearing aids are needed annually, yet only around 750,000 are provided. Solar Ear's approach is designed to meet this gap in supply, as it shares its technology, business model and program protocols for free to like-minded social businesses. It is also developing a smart-phone app designed to make screening accessible to millions. Solar Ear trains, hires and employs young people who are deaf. Besides, they reinvest 1/3 of our profits back into the business, 1/3 towards our social mission and 1/3 towards the empowerment of our workers.
